Specification forming part of Letters Patent No. 148,50*?, dated March 1T, 1874; application filed December 27, 1873.

To all whom it may concern:

Beit known that I, JULIUs Jonson, of the city, county, and State of New York, have invented an lmprovement in Liquid-Meters, of which the following is a specification: Y

This invention relates to that description of liquid-meters in which a piston reciprocating within a cylinder effects the measurement, and in which the reverse movements of said piston are controlled by a rolling valve.

The invention consists in a combination of an elongated piston and its cylinder with a rolling valve having its axis perpendicular to that of the piston, and which is in direct connection, by an arm, with a groove in the piston, whereby said valve is operated in a simple, direct, and positive manner, by the piston, Without the intervention of gear, and all stuffing-boxes, either for the valve or piston, to establish outside communication between them, are dispensed With.

ln the accompanying drawing, which forms part of this specification, Figure l represents a top view of a meter constructed in accordance With Iny invention, the upper cover of the receiving-chamber of the valve-box being removed. Fig. 2 is a longitudinal exterior view with the receiving-chamber of the valvebox in section, as indicated by the line x x.

, Fig. 3 is a horizontal section, on the line y y,

through the valve and passages, connected therewith.

Similar letters of reference indicate corresponding parts throughout all the iigures.

A is the Ineasuring-cylinder of the meter, and B its hollow or double-headed and elongated piston, arranged to reciprocate Within, or so as not to pass entirely beyond or out of, circumferential,bearingstrips b b on the interior of said cylinder. C is the receivingchamber of the valve-box, having an inlet, d, the outlet from the meter being represented by the letter c. This receiving-chamber C is in free communication between the bearingstrips Z1 b, with the upper portion of the cylinder A on its one side. D is the rolling valve, having its axis in a plane Which is perpendicular to that in which the axis of the piston B lies. This valve, which Works Within a box, E, may be of any suitable construction, and the passages it controls be variously arranged, so that a rolling or oscillating motion given to the valve Will change the course of the liquid into and out of opposite ends of the cylinder A alternately.

It is preferred, however, to use a cylindrical or rolling valve similar to one previously used in liquid meters, and constructed so that, While said valve is lifted by the piston, it is free to Vdrop and turn, when dropping in part by its oWn Iveight, and in part by the pressure of the incoming liuid, or either, to eect its reversal at the close of the pistons stroke, a vibrating cam or ring, having reversed incliues upon it, being used to produce su'ch movement of the valve, substantially as described in Letters Patent of the United States, No. 111,134, issued January 24, 1871, and the passages which the valve controls may be similarly arranged. Thus E is the cam-ring, formed with double reversed inclines f on its edge, for operation in connection With stops g on the valve, so that as said cam-ring is vibrated it acts on rollers h h, attached to or connected With the valve to lift the latter in a straight line; but so soon as the reversed inclines on the cam-ring pass at their highest points from under the rollers, then the valve drops and turns to reverse its action to change the course of the current through the meter.

The movement of the valve by the piston is effected in a direct or positive manner, Without the intervention of gearing or stuffing-boxes, to establish an Outside connection between the piston and valve, by means of an arm, G, connected with the valve or its Operatin g cam or device Within the receiving-chamber C of the valve, said arm entering by a stud or roller on its end Within a circumferential groove or notch, H, in the intermediate portion ofthe piston B,\vhereby the latter, as it reciprocates automatically, shifts the valve, as required.

l claim- The combination, With the intermediately grooved or notched elongated piston B and its cylinder A, of a rolling valve having its axis in a plane Which is perpendicular to the axial line of the piston, and an arm, G, for operating said valve directly from the piston, substantially as shown and described.
